In some part of the world it is known as a tartan and in other parts of the world in is known as plaid. Recently plaids are not just for kilts or lumberjacks. The design is a pattern consisting of criss-crossed horizontal and vertical bands in multiple colors.
In the past I have tried to duplicate patterns such as these just to learn how they are made. It gave me better knowledge of how design works as you can see here.
Plaid or tartan is in style and always will be no matter what age you are.
